Abstract: We prove the maximal local regularity of weak solutions to the parabolic problem associated with the fractional Laplacian with homogeneous Dirichlet boundary conditions on an arbitrary bounded open set Proofs combine classical abstract regularity results for parabolic equations with some new local regularity results for the associated elliptic problems.
